this method is much easier than other articles on the internet even on support.oracle.com

those files are not actually been used as you can test it by rename one file first. And during the opatch process, those files will be replaced with new version. It means even you delete those files should also be ok.

This article only suppose that you are meet the same issue as mine.

1 stop oracle services. use “net start | findstr -i ora” [need]

2 stop msdtc service. [maybe need]

3 if you like me use fail safe. then go to cluadmin offline the service role under cluster resource. [not sure it is need]

It looks much simpler and useful until I change it as below for daily use.

but it does not work. and after restart the office, one new subkey will recreate automatically.

then goto the HKEY_CURRENT_USER\Software\Microsoft\Office\15.0\Common\Internet\WebServiceCache\AllUsers\office15client.microsoft.com\config15--lcid=1033&syslcid=1031&uilcid=1033&build=15.0.4569&crev=1\

there is a dword registry “Properties”, normally its value is 1, change it to 0.

restart office 2013, you should be able to get the live account logon page back.

after the success logon, you can try to change the registry back to 1, this will not affect office.

i did not try to switch account, but i think change this value can still make everything work.

i can not sync file correctly and i can not even stop sync the sharepoint site. while after some research, i find a way that reset all settings in skydirve pro.

just clean all data in folder “c:\users\%username%\AppData\Local\Microsoft\Office\Spw”

yes, just delete all files in this folder, you can reset all settings.

Just try:

$webclient = New-Object System.Net.WebClient

$creds = Get-Credential

$webclient.Proxy.Credentials = $creds

And then try Update-Help. If it works like expected, you could also work with scripted credentials (replace “username” and “password”).

if OS is windows 2008 R2 RTM build7000 and installed MS12-020 (kb2667402,2621440), after apply windows 2008 R2 SP1, you could not be able to logon the server use RDP connection the server remotely. event 4005 source winlogon content “the windows logon process has terminated unexpectedly”.

what you need to do is:

logon the local console and uninstall MS12-020 (kb2667402,2621440), reboot and re-install MS12-020 (kb2667402,2621440) and reboot.

While for HP servers you need to do is order H221 HBA card and directly connect the D2000 enclosure. in my case, it is DL380G8, H221 HBA, and D2700 enclosure.

These controllers do not support a non-RAID, JBOD mode. They cannot present disks to the host directly. Each disk must first be included in a Logical disk. You can create a single logical volume for each disk you have and give this to ZFS. Performance should be equivalent. However, it means putting header information onto the physical disk. If your controller fails, you must use another MegaRAID, configured exactly the same. And there is not guarantee that another SAS or SATA controller will see the data correctly and present the volumes in a way that the zpool can be correctly constructed.

You create a virtual SAN on the host (parent partition), for each HBA on the host that will be virtualized for VM connectivity to the SAN. This is a 1-1 binding between virtual SAN and physical HBA, similar to the old model of virtual network and physical NIC. You then create virtual HBAs in your VMs and connect them to virtual SANs.

And that’s where things can get interesting. When you get into the FC world, you want fault tolerance with MPIO. A mistake people will make is that they will create two virtual HBAs and put them both on the same virtual network, and therefore on a single FC path on a single HBA. If that single cable breaks, or that physical HBA port fails, then the VM has pointless MPIO because both virtual HBAs are on the same physical connection.

The correct approach for fault tolerance will be:

2 or more HBA connections in the host

1 virtual SAN for each HBA connection in the host.

1 virtual HBA in each VM, with each one connected to a different virtual SAN

MPIO configured in the VM’s guest OS. In fact, you can (and should) use your storage vendor’s MPIO/DSM software in the VM’s guest OS.

Now you have true SAN path fault tolerance at the physical, host, and virtual levels.

What I am planning:

1- use as less as possible vSwitch. I am planning to use 1 vSwitch.

1a-in my environment, all ESXi servers will connect to the same network VLAN, single and multiple vSwitches is same function level on both performance, security.

1b-vSwitch count is not important. but Port Group is more important and could provide the same level of performance, security.

1c-multiple vSwitch is same as single vSwitch function from ESXi software level, all the vSwitch is logically split by ESXi but they are the same from physical level.

2- use only one type. I am planning to use vDS only.

reason:

2a-in my environment, all ESXi servers will connect to the same network VLAN, for vDS or vSS it looks like the same.

2b-it looks like vDirector need all ESXi servers have same vDS vSwitch.

3- not or do the split the FC and network flow.

reason:

3a- each ESXi server will have 4 SPF ports on two CAN cards to provide enough redundancy on both card level and port level.

3b- 2 ports on the same CAN card will connect to the same Cisco 5K switch. This will provide port level redundancy when split FC and network flow.

3c- 2 CAN cards will connect to different Cisco 5K switch. This will provide card level redundancy.This will provide port level redundancy when not split FC and network flow.

3d- if I choose to split the FC and network flow on each port as there are two cards with 4 ports, the redundancy level is still on both port and card level with a 99.9999% no-failure rate

3e- if I choose to not split the FC and network flow on each port but use 1 port as network another as FC connection on the same card, the redundancy level is still on both port and card level with a 99.99% no-failure rate. but will make the whole operation more easier.

3f- so the split the FC and network flow decision should based on the cards and the ports on the server. if you have only one CAN card with 2 ports on the server, you will need to split the FC and network flow and get only port level redundancy. if you have 2 CAN cards with total 4 ports on the server, either split or not should be fine to the whole design.

When user mailbox have multi email addresses, for example a@corp1.com and a@corp2.com, primary email address is a@corp1.com. And he wants to send a mail with mail from a@corp2.com. Then he will get a NDR that he does not have permission to send as a@corp2.com.
This is by designed. Do not try to change the behaved.

To help user get what he want, here is a workaround.

1 create a new public mailbox for him.
2 assign full access and send as privilege on the public mailbox for him
3 change primary email address on the public mailbox to a@corp2.com at the meanwhile change his email address to a1@corp2.com
4 ask helpdesk engineer to add the public mailbox opened in his mailbox account from outlook account settings.
